The central question will be focused around the design and implementation of neuronal circuitry involved in the task of decoding sensory information. Sensory information is encoded in the form of sequence of action potential spikes by the peripheral nervous system. This information is then passed onto the central nervous system (CNS) to generate an appropriate response. The action potential spikes are identical in shape and therefore it is assumed that all the information about the environment is embedded in the timing of occurrences of these spikes. The question then is, what neural architecture exists in the CNS to decode this information?
